wouldn’t worry about it, the guy just probably hates his wife & kids and wants an excuse to have weekends away
seriously though, yeah it’s complicated. As I think I’ve mentioned before my mum is a staunch Utd fan and old Stretford ender - typical of the Manc Irish Catholics that were born in Ireland and came to England & settled in Manchester after the war. Whereas the generation born in Manchester (and environs) ie all my cousins are City fans except in those few cases where their Irish relatives took them to games when they were bairns.
For my sins my dad grew up in Liverpool so despite being born in Bury me & my brother were indoctrinated into never walking alone even though my mum was actually much more of a football fan than he was
so, there’s no real honour in proximity, it’s just interesting to see how these influences radiate and comingle with other aspects - like I said there’s often lots of choice in certain areas of the country but then even within those areas it can be highly territorial so choice is taken away. My 5yo loves watching the football with me but if she were ever to pick a Stockholm team to support there’s no way any of the local kids would let her be AIK or Djurgården, she’d practically be forced to be Hammarby (even though Hammarby and Djurgården have a groundshare)
